Hello, and thank you for choosing JA for your support needs. Happy to assist you with this issue.
Have you done an Alignment of the new Printhead? Please follow the instructions below:
If printed lines are misaligned, execute Head Inc. Adj. to adjust the angle of inclination of the Printhead. Executing Head Inc. Adj. requires you to examine a printed test pattern and enter an adjustment value.
Paper to Prepare
An unused roll at least 10 inches wide
One sheet of unused paper of at least A4/Letter size
Perform adjustment as follows.
1.Load the paper.
2.On the Tab Selection screen of the Control Panel, press or to select the Settings/Adj. tab ( ).
3.Press the OK button.
The Set./Adj. Menu is displayed.
4.Press or to select Adjust Printer, and then press the OK button.
5.Press or to select Head Inc. Adj., and then press the OK button.
After the Carriage is moved, a message is displayed requesting you to open the Top Cover.
6.Open the Top Cover.

A test pattern is printed for adjustment.
8.Examine the test pattern for adjustment. Determine the straightest set of lines.
9.Open the Top Cover and move the Angle Adjustment Lever to match the number (or the square) of the straightest set of lines.
If no single set of lines is perfectly straight, move the Angle Adjustment Lever to a position between the numbers (or between the number and the square) of the two sets of lines that are least misaligned.
10.Close the Top Cover.
The Printhead is now straight, and adjustment is complete.
